Maria de Villota's family is not ruling out legal action after the former Marussia Formula 1 team was cleared of any wrongdoing in her testing accident in 2012.
The Health and Safety Executive which investigated the circumstances of the accident said on Tuesday that it did not feel any further action was necessary.
De Villota crashed into a team truck while carrying out straightline testing at the Duxford Aerodrome in July of 2012, losing her right eye and dying over a year later as a consequence of the neurological damage at the age of 33.
De Villota's family said in a statement on Tuesday evening that they were yet to see the HSE report.
They added that, once they have analysed it, they would consider taking legal action in order to avoid further "negligence".
"On 14th May, the authorities informed us that the investigation had come to an end, at the same time telling us that it did not have sufficient evidence to initiate criminal proceedings with guarantees of convictions," de Villota's family said in a statement.
"To date, we are still waiting to know the contents of the report and, consequently, the final results of their investigations.
"As soon as the HSE grants us access to the report and its contents, we will study it in order to assess the commencement of appropriate legal actions to assign civil responsibility in order to prevent, as was Maria's wish, an accident like this occurring again due to negligence."
